Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160138, here are decompositions:
- 47 + 160091 = 160138
- 59 + 160079 = 160138
- 89 + 160049 = 160138
- 107 + 160031 = 160138
- 137 + 160001 = 160138
- 227 + 159911 = 160138
- 239 + 159899 = 160138
- 269 + 159869 = 160138
Showing the first eight; more decompositions exist.
